Abstract BACKGROUND: This study was designed to assess the clinical judgment of medical students in
surgery clinical decision‑making by a standard examination after lecture‑based learning (LBL) or
problem‑based learning (PBL).
MATERIALS AND METHODS: A prospective randomized trial study on 175 medical students
whom were randomly allocated to three groups was performed during November 2017 and January
2018. LBL group (n = 103), PBL group led by an attending (n = 39), and PBL group (n = 33) led by
an intern. Chi‑squared test and independent student t‑test were used to compare between the two
groups. All the analyses were performed by the two‑sided method using the Statistical Package for
the Social Sciences software (SPSS version 22; SPSS, Inc., Chicago, IL, USA), and a P < 0.05 set
as statistically significant.
RESULTS: The students in the PBL group scored significantly higher on the posttraining multiple‑choice
examination, compared to the LBL group (P = 0.048). However, there was no significant difference
between the PBL group led by an attending and the PBL group led by an intern (P = 0.892).
CONCLUSION: We concluded that PBL remarkably increased the students’ scores in the
problem‑solving examination, as compared to the conventional method. We found no significant
differences in PBL facilitated by an attending or an intern.
